Be it known that I, COWAN D. WILSON, a citizen of theUnited States, residing at Big in the county of Wise and. State of Virginia, have invented new and useful Improvements in renches, of which the following isa specification.

The present invention relates to improvements in nut wrenches which are operated by a turning handle, and it has for its object to provide a simply constructed and operated wrench which is durable and easy to handle, andone which may be quickly and easily adjusted to clamping or unclamping position with relation to an object upon by the wrench.

Another object of the invention is to embody in a wrench a strong and durable construction which can be manufactured cheaply and wherein all of the parts shall be removable and changeable.

to be operated A still further object of the invention is to provide a stationary jaw with a rod or tubular shank, to arrange a slidable jaw upon the shank and retain the same thereon against rotary movement, and to provide a handle which shall comprise a lar member that has a swivel connection with the movable jaw, and further to procant soaked pad which, when contacted between the end of the handle and the end of the shank serves to lubricate the same and so materially assist in the connection and accurate operation of the handle upon the shank. I v 7 Other objects and advantages will appear as the nature of the invention is more fully understood. v

The improvement resides in the construction, combination and arrangement of parts set forth in the following specification and falling within the scope of the appended claims. 7

In the drawing: Figure 1 is a side elevation ofa wrench constructed in accordance with the present invention, Fig. 2 is a similar view, thetubular handle being shown in longitudinal section, Fig. 3 is a transverse section on the line 3-3 of Fig. 2, Fig. i is designates the fixed jaw whic. may be in Specification of Letters Patent.

The what Inwill term its centrally with a 101igitudinally arranged depressions, the upper preferably beveled or face of the jaw5 to the lower face of 2 is rounded to receive web 7 between the portionof the jaw .5 provided with the opening 6, and which for convenience may be termed a collar, and the second collar 8 is centrally provided with a I Patented cat. 5, i915.

I-- will term, its underface arched from its con- .nection with the inner 30 longitudinally extending tongue 9, the said tongue preferably having beveled or inclined sides to agreewith the inclined side walls provided by the depression 4:. It will forth, the movable jaw 5 may be inserted over .the' threaded end ,3 of, the shank '2 funtil k: itstongue 9 is brought into engagement between the walls of be noted that an arrangement as justset' The outer face of the collar 8 at the lower portion thereof or at its connection with the web which is adapted to have a swlveled engage-' rnent with'an annular bead or rib 11 formed upon the open mouth of the operating handle 12 This operating handle has its bore of which may be indicated by" the numerals 13 and 14 respectively, the por-.

tion 13 being of a size to snugly receive the non threade 7 is formed with an upturned lip 10 pertiea as the ehaak E2, the

portion 14 being threaded and having its threads co-act with the threads 3 at the reduced end of the shank. The hollow operating handle 12 has arranged therein and at its outer and closed end, a lubricant pad 15. This pad is soaked with oil before being inserted within the hollow handle 12, and the bore of the handle is of "a suflicient length to permit of the end of the threaded portion 3 of the shank compressingthe pad when the jaw 5 is arranged upon or near the jaw 1, thus expressing the oil from the pad to cause the same to be delivered around the threads of both the shank and handle as well as to be directed through the bore 13 of the handle to withinthe depression 4:, and so lubricate the walls of the said depression to permit of the tongue 9 sliding freely in a longitudinal direction upon the shank The lubricant is also delivered to within the lip 10 and the bores of the collars 8 and 6. When all of the lubricant has been expressed from the pad, the handle 12 may be readily removed by unscrewing the same, and a lubricant may be delivered from the open mouth or end of the handle to the pad or if desired, the pad may be removed and again soaked in oil.

In a number of instances it has been found desirable that the lubricant be delivered only to the threads of the shank and handle.

and in such instances,a dam in the shape of a washer may be arranged around the shoulders provided between the two bores of the handle and that portion provided between the rounded and threaded portion of the shank, or furthermore, the pit between the rounded portion of the shank and the non threaded portion of the handle may be suflicient to prevent the lubricant passing beyond the shoulder between the threaded and non-threaded portions of the'shank.

Having thus described the invention, what I claim is:

1. The herein described construction of wrenches including a fixed jaw, a cross sectionally round shank formed with and extending from the shank, the said shank having its outer end threaded and the nonthreaded portion of said shank being provided with a longitudinally arranged depression, a movable jaw for the shank including a pair of spaced collars connected by a web, and the said web between the said collars being formed with a longitudinally extending tongue which is received within the depression in the shank of the stationary jaw, and a hollow handle member threaded upon the end of the shank and co-acting with the movable jaw to slide the said movable jaw upon the said shank when the said handle is rotated.

:2. A wrench constructed as herein described including a having a cross sectionally rounded shank provided with a reduced threaded extension, a slidable jaw, said slidable jaw including spaced collars connected by a web, said collars having round openings to receive the rounded shank of the stationary jaw, the web being formed with a longitudinally extending tongue between the said collars which is received in the depression in the said shank, the outer collar being formed with a lip, a hollow operating handle having a bore of two dimensions, the smaller of which being threaded to engage with the threaded end of the shank, a compressible element between the end of the bore and the end of the threaded shank, andthe open end of the said handle being formed withan annular bead which is adapted to coengage with the lip of the mentioned outer collar of the movable jaw.

In testimony whereof I atfiX my signature in presence of two witnesses.
